SFP Transceiver TP-Link SM311LM 1250 Mbit/s MiniGBIC Module

The TP-Link SM311LM SFP transceiver is a MiniGBIC fiber module designed to extend network link distances for managed and smart switches. Supporting a data rate up to 1250 Mbit/s and operating at 3.3 V, this metallic SFP module enables fiber connections over several kilometers, meeting typical LAN distance requirements while offering FCC and CE certifications for compliance and reliability.

Advantages

The SM311LM provides a compact MiniGBIC/SFP form factor for easy hot-plug installation into compatible switches, allows selection of fiber modules as needed to reduce deployment cost, and supports transmission over long distances to bridge remote network segments. Its metal housing and industry certifications contribute to stable performance and regulatory compliance.

Suitable for

• Extending network links between switches across buildings or campus areas
• Connecting distant LAN segments where copper cabling is impractical
• Upgrading managed or smart switch ports to fiber connectivity

Key specifications

• Product type: SFP (MiniGBIC) fiber transceiver
• Model: TP-Link SM311LM
• Data rate: up to 1250 Mbit/s
• Supply voltage: 3.3 V
• Housing: metal
• Certifications: FCC, CE

How to use

Insert the SM311LM module into a compatible SFP slot on a managed or smart switch while the switch is powered on or according to the switch vendor's hot-plug instructions. Connect appropriate single-mode or multimode fiber cables and terminate them with matching connectors. Configure the switch port settings if required by your network (for example duplex or speed parameters are generally negotiated automatically for SFP fiber links). Verify link status through the switch management interface or port LEDs.

Usage recommendations

Choose the appropriate fiber type and connector to match the module and distance requirements, follow the switch vendor's guidance for SFP compatibility, and handle the transceiver carefully to avoid contamination of fiber end-faces. For cost-effective deployments, populate only the ports that require fiber modules.
